SAW FRAME.

Application led November rIhis invention relates to improvements in saw 'frames and has particular reference to a portable type of frame adapted to be mounted upon a tractor or the like.

An important obj ect ot' the invention is the provision ot a saw 'trame adapted to be securely fastened upon a tractor or similar vchicle and arranged so as to be operated. by the motor thereof. f

A still further object ol the invention is to provide a saw trame which may be conveniently secured upon a tractor and arranged so as to be readily operable in association therewith.

Still another object of the invention is to provide a saw frame ot rsimple and durable construction particularly designed to be firmly secured on a tractor` or the like and which may be manufactured at a reasonable cost.

Other objects and advantages ol the invention will become apparent as the description progresses.

ln the accompanying drawings forming a part of this specification and in which like reference characters are employed to designate corresponding vparts throughout the same: j

Figure l is a top plan view of my improved frame struct-ure shown in operative position upon a tractor;

Figure 2 is a side elevation of the same;

Figure 3 is a side elevation et the structure looking at the side opposite the side shown in Figure 2; y

Figure d is a longitudinal sectional Aview taken through the center ofthe` frame, and

Figure 5 is a transverse sectional. view taken on the line 5-5 ot Figure 3.

ln the drawings, wherein for the purpose oit illustra-tion is shown the prefer-redembodiment ot. my invention, the numeral generally indicates a conventional type 'of tractor provided with a drive pulley 11 eX- tending from the intermediate portion connected with the drive motor so as to be rotated thereby. This tractor is of a well known construction and forms no part ot my invention, being merely illustrated to indicate the application of my improved appa-v ratus in association therewith.

My invention rela-tes particularly to a saw frame adapted to be securely attached to this particular type oi tractor, and with slight modification to be mounted upon various other well known types ot tractors. Referframe beam .and eXtending 'forwardly thereof;

ring now with particularity to the trame structure embodying my invent-ion, the numeral l2 indicates a main support beam prelierably constructed ot wood and rectangular in cross section. The inner side of the beam is recessed at its rear extremity as at 13 to permit convenient mounting ot this beam on 'the tractor.

.extending projections, the forward projection being positioned in contact with the outer side of the beamA l2 and secured thereto as at 16 lwhile the oppositely directed connecting portion 17 is secured by oneot the bolts ot the transmission housing, as shown to advantage in Figures l and 2. 3

Secured to the intermediate portion ot the Vtrame beam l2 and extending upwardly is a bracket 18vincluding an inclined bar 19 having its lower end bolted to the beam and its upper portion extending horizontally, and a vertical support bar Q0 bolted at its lower end to the beam land at its upper end to the upper portion 01"' the bar 19.

lvounted in parallel position upon the opposite side ot the tractor is an auxiliary Q1. secured to the tractorirai'ne This beam carries a bracket 22 corresponding to the bracket 18 and arranged opposite the same. ...s shown in Figures l and 3 of the drawings, the beam 21 is comparatively short and provided with a recess, corresponding to the recess 13 of the beam 12,to'perniit con#- venient connection with the tractor. The bars l@ and 22, are secured to thetorward portion ot' the tractor by a transversely eX- tending'rod Q3 having a head formed on one end, the ends ot the rod extending through alincd openings formed in the ends of the said. bars, the other end of the rod being Y threaded for the application of asecuring nut. This rod extends through the tractor trame immediately behind the radiator, and No L'the pulleys 1l and 28.

if necessary may extend through a portion of the tractor structure to prevent displacement. Theobeams l2 and 2l are braced by a rod 24:,seoured at its ends in the beams.

Mounted in transverse alinement on the upper sides of the frame beams l2 and 2l adj acent their forward ends are bearings 25 rotatably supporting a shaft 26. The end of the shaft which projects beyond the fra-me beam 2l carries a fly wheel 2?' secured to the shaft .so as to rotate therewith and efficiently balance the same. Fixed upon the shaft 26 between the fly wheel 27 and the beam 2l is a pulley 28 in alinement with a drive pulley ll.. The V pulley 28 is driven by a. belt 29 trained over the pulleys. Detachably mounted upon the other end of the shaft 26 is a circular saw 30 of comparatively .large diameter provided at its central portion with a hub 3l and at its periphery with teeth 82. rfhe saw hub 3l maybe provided with a rectangular bore engageable with a suitably formed extension on the shaft 26 so that the saw will be positively driven by rotary movement of the shaft.

,In order thata work supporting bed may be provided, an attaching board 33 is mounted upon the outer side of the beam 12, and a metallic plate 34 is disposed upon and secured to the upper edge of the board and the upper side of the beam. With particular reference to Figure l, it will be seen that this construction will provide a convenient bed arranged adjacent tothe saw 30.

In use, it is obvious that my improved saw frame construction may be readily assembled upon the conventional type of tractors without altering the structure thereof or interfering with the convenient operation. The frame structure may be readily assembled on the tractor in the manner previously described and may be readily removed when desired. After the saw frame, and the parts mounted thereon, has been securely fastened upon the tractor frame, the drive belt 29 is applied over The tractor then driven to the desired position, and the gears shifted so as to impart rotary motion te the drive pulleyll. Rotary movement of the pulley ll will cause similar simultaneous movement of the shaft 26 and the .fly wheel and saw 30 secured thereon.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same and that various changes as to the shape, size and arrangement of parts may be resorted .beam disposed with its rear end` close to the body at said side thereof at which the pulley is located and extending forwardly beyond the body a shorter distance than the firstmentioned beam, means securing the rear end of the Afirst mention-ed beam to a part of the tractor, vertically disposed bracket bars asso-` ciated each with a respective one of said beams, the lower end of the bar which is associated with the first mentioned :beam being secured to the inner side of said beam, the lower end of the other bracket bar being secured to the outer side of the other beam, the attached lower ends of the bracket bars -being oppositely located, a rod extending through the front portion of the body of the tractor and at itsends through the upper ends of said bracket bars, a rod extending transversely between the rear end of the second mentioned beam and the intermediate portion of the first mentioned beam and in contact with the forward side of the body of the tractor, each of said bracket bars being downwardly and forwardly inclined from a point in advance of the rear end thereof, upstanding spacing uprights secured at their lower ends to the said beams and secured at their upper ends each to a respective one `of the bracket bars near the rear end thereof, bearings mounted upon the beams adjacent :the points of connection of the lower ends of the bracket bars with the beams, a shaft rotatably ournaled in the bearings, a pulley upon the shaft in advance of the motor pulley of the tractor, a saw blade fixed upon the shaft at its end which is next adjacent the first nientioned beam and occupying a plane parallel to and spaced with respect to the outerl face of said beam, and a Work supportingbed plate upon the forward portion of. said beam in advance of the saw blade.
